Description

Technical Field

[0001] This utility model relates to the field of automotive seat frame frames, specifically to a seat frame frame with a buffer rear support. Background Technology

[0002] The car seat frame is the core load-bearing structure of the seat system. The seat frame supports the entire weight of the occupant through a high-strength steel or aluminum alloy skeleton and transfers the load to the vehicle floor through a sliding rail system to ensure the stability of the ride. The seat frame directly bears the pressure on the buttocks, while the backrest frame shares the load on the back. The two work together to maintain the balance of the human body in sitting posture.

[0003] The existing seat frame and rear outriggers are mostly rigidly connected. During the acceleration of the car and during sudden braking, the human body will have a backward force. This force will be transmitted to the rear outriggers through the seat frame. Because of the rigid connection between the rear outriggers and the seat frame, the rear outriggers lack cushioning and have low impact resistance. This will put a lot of burden on the connection between the rear outriggers and the seat frame, resulting in certain safety hazards. Utility Model Content

[0004] Based on the above description, this utility model provides a seat frame skeleton with a buffered rear support leg to solve the problem of insufficient buffering capacity between the existing seat frame and the rear support leg.

[0006] A buffer part is installed on the top of the rear support leg. The end of the buffer part away from the rear support leg is connected to the bottom of the seat side plate. A limiting part is installed on the side wall of the rear support leg. The limiting part includes a side plate and a plug rod. One end of the side plate is fixedly connected to the side wall of the seat side plate. One end of the plug rod is movably inserted through the side wall of the rear support leg, and the other end of the plug rod is inserted into the side plate away from the rear support leg.

[0030] Please see Figure 1 , Figure 2 and Figure 3 A seat frame frame with a buffered rear support leg includes a seat side plate 1, and a rear support leg 2 is installed at the bottom of the seat side plate 1.

[0031] A buffer part 4 is installed on the top of the rear support leg 2. The end of the buffer part 4 away from the rear support leg 2 is connected to the bottom of the seat plate 1. A limiting part 3 is installed on the side wall of the rear support leg 2. The limiting part 3 includes a side plate 301 and a plug rod 306. One end of the side plate 301 is fixedly connected to the side wall of the seat plate 1. One end of the plug rod 306 is movably inserted through the side wall of the rear support leg 2, and the other end of the plug rod 306 is inserted into the side plate 301 after moving away from the rear support leg 2.

[0032] The buffer section 4 includes a fixing block 401, a spring 402, a circular plate 403, a buffer rod 404, and a connecting plate 405. One side of the fixing block 401 is fixedly connected to the inner wall of the rear support leg 2, and a circular hole is provided inside the fixing block 401. The circular plate 403 and the spring 402 are both installed in the inner cavity of the circular hole, and one end of the spring 402 is fixedly attached to one side of the circular plate 403. The side of the circular plate 403 away from the spring 402 is fixedly connected to the end face of the buffer rod 404. The end of the buffer rod 404 away from the circular plate 403 is fixedly connected to the side of the connecting plate 405. The connecting plate 405 is located away from the side of the buffer rod 404. One side of the shock rod 404 is fixedly connected to the bottom of the seat side plate 1. Both the connecting plate 405 and the seat side plate 1 have reserved holes. The installation work between the connecting plate 405 and the seat side plate 1 is completed by inserting bolts into the reserved holes of the connecting plate 405 and the seat side plate 1. When the seat frame is subjected to impact force, since the shock rod 404 is connected to the seat side plate 1 through the connecting plate 405, the seat frame will transmit the force to the shock rod 404, so that the shock rod 404 drives the circular plate 403 to compress the spring 402, and uses the elastic force of the spring 402 to buffer the force.

[0033] Please see Figure 2 , Figure 3 and Figure 4 In this embodiment, the side wall of the circular plate 403 is in movable contact with the inner wall of the circular hole. The end of the spring 402 away from the circular plate 403 is fixedly installed on the inner wall of the circular hole. When the buffer rod 404 is impacted and moves, the circular plate 403 will slide along the inner wall of the circular hole. Since the circular plate 403 is in movable contact with the inner wall of the circular hole, it can be ensured that the circular plate 403 is in a stable state during the sliding process and will not be tilted.

[0034] Please see Figure 2 and Figure 3 The limiting part 3 in this embodiment also includes a mounting hole 302 and a movable block 303. The mounting hole 302 is opened on the side wall of the side plate 301, and the movable block 303 is movably installed in the inner wall of the mounting hole 302. The movable block 303 is provided with a threaded hole, and the inner cavity of the threaded hole is movably inserted by the insertion rod 306.

[0035] Please refer to the figure. Figure 4 and Figure 5 In this embodiment, the two ends of the insertion rod 306 are provided with threaded grooves, and the threaded grooves are used to connect with the nut. The other end of the insertion rod 306 is threaded to the insertion hole. The insertion rod 306 is used to connect the rear support leg 2 and the seat plate 1.

[0036] Please see Figure 4 and Figure 5 In this embodiment, a groove 307 is provided on the inner wall of the mounting hole 302, and a protrusion 308 is fixedly connected to the movable block 303. The end of the protrusion 308 away from the movable block 303 is inserted into the inner cavity of the groove 307.

[0037] Please see Figure 4 and Figure 5 In this embodiment, the limiting part 3 also includes a first buffer block 304 and a second buffer block 305. One end of the first buffer block 304 is fixedly connected to the side wall of the movable block 303, and one end of the second buffer block 305 is fixedly connected to the inner wall of the mounting hole 302. The end of the first buffer block away from the movable block 303 and the end of the second buffer block 305 away from the mounting hole 302 are movably fitted together. When the seat plate 1 is subjected to an impact force, the force will be transmitted to the side plate 301. After the movable block 303 in the side plate 301 is fixed to the rear support leg 2 through the insertion rod 306, the second buffer block 305 and the first buffer block 304 in the side plate 301 will be squeezed to buffer the force.

[0038] Please see Figure 4 and Figure 5In this embodiment, both the first buffer block 304 and the second buffer block 305 are rubber blocks, and the end where the first buffer block 304 and the second buffer block 305 are in contact is designed to be pleated, so as to facilitate the compression of the first buffer block 304 and the second buffer block 305.

[0039] Please see Figure 4 and Figure 5 In this embodiment, the protrusion 308 is designed as a hemispherical shape, and the inner wall of the slide groove 307 is designed as an arc-shaped groove that engages with the protrusion 308. By utilizing the cooperation between the slide groove 307 and the protrusion 308, the movable block 303 and the side plate 301 can undergo relative displacement, and the movable block 303 and the side plate 301 will not detach.

[0040] When subjected to impact, the seat side plate 1 on the seat frame transmits the impact force to the buffer rod 404. The buffer rod 404 drives the circular plate 403 to compress the spring 402 inside the fixed block 401. At the same time, the side plate 301 transmits the impact force to the first buffer block 304 and the second buffer block 305. The compression and absorption of the impact force by the spring 402, the first buffer block 304 and the second buffer block 305 achieve the buffering effect.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
